1) the sensor on the back of the throttle body ( i think its called the TPS) what does it do and how do i know when its adjusted right?

2)what should the rpm of the idle be at?

3)i just finished my swap. (gsr bottom and b16 head) im running a p28 how long can i run the ecu the motor with out having it chipped?


thanks so much for your guys help through my entire swap!

 

1. yes it is a tps. it tells the ecu how much throttle is open so the ecu can tell how much fuel to add for the amount of air being flowed in.

2. cars are to idle ~750

3. a life time if you wanted. it's just best to run a proper basemap.

 

thanks kidsafe yee

any more input guys!
